MACHINE FOR DIVIDING DOUGH.

Specification of Iietters Patent.

Patented Dec. 10, 1912.

To all whom it may concam:

Be it known that I, JAMES WILSON, a subject of the King of Great Britain, residing at Glasgow, Scotland, have invented a certain new and useful Improved Machine for Dividing Dough, of which the following is a specification.

This invention relates to dough dividing machines of the class wherein the dough is fed from a hopper into cavities in a rotating drum, each of said cavities being provided with a plunger so actuated by a.v cam as to automatically eject the lumps of dough, whichlatter fall down onto a conveyer and are removed thereby.

Under this invention a single drum is preferably used and there is a. hopper thereover provided with a plate or the like which passes down one side of the drum to the underside thereof, and forms with the surface of the drum, a gradually converging chamber, the said plate being arranged eccentric to the drum, and having, at its lower end, a scraping and cutting arrangement adapted to direct the dough to the cavity being filled; the drum being made with corrugations or flutings on its surface and with circumferential side flanges which may be plain, corrugated, or fluted, so as to assist in the feeding of the dough to and in the said converging chamber.

In order that the'invention maybe clearly understood we have hereunto appended explanatory drawings which show,- by way of illustration or example, one mode of constructing the machine in accordance with the invention,

On the said drawings :Figure 1 is a ver:

tical section taken on the line 1, 1, Fig. 2.

40 Fig. 2 is a vertical sect-iontaken on the line 2, 2, Fig. 1. Fig. 3 represents a plan view of 'a portion of a plate employed in detached position.

In the machine shown on the drawings a is the'drum. b the hopper, c the conveyer band which receives the'lumps of ejected doughfll, d the fast and loose pulleys on the driving shaft f, e, '6 gear wheels by means of which the drum. is rotated, f, 7, the cavities in the drum 0, g, g, the plungers in the cavities, It t? tationary cam. which operates the plungers, i the cam by means of ,which the quantity of dough received by the cavities may be varied and 2'? the handle by 5 means of which the earn i'ca b6 j extensible device consisting preferably of a b is a scraper.

The'drum a is made with a pair of trunnions a aflwhich work in bearings in the side cheeks or frames 7', 7', of the machine, and secured on the trunnion a is the gear wheel e, by means ,of which the drum is driven, and provided on the drum is a pair of circumferential flanges a a, which. are arranged one -on each side of the drum and whose outer edges work in recesses 71 provided in the walls of the hopper 6. One side of. this hopper bis extended downward in the form of a curved plate or the like k p which forms, with'the surface of the drum a and the side flangesa, 0. thereof a graduall converging packing chamber t. The plate is made with supporting cheeks is which are mounted'upon the brackets j on theeeide frame 7' of the machine, and the portionl of the plate is made with a hinged door 2 which preferably extends for only about a half of the width of the plate 7c, the hinge consisting of a bolt or pin k passed through snugs It on the portion 1 and the door 2. The door 2 is made on its back with a central strengthening web 70' whose lower end is formed with a fork or open slot adapted to receive a screw 7: extending from the back ofgthe plate 70 and fitted with a thumb screw it by means of which the door 2 is locked.

Hinged to the lower end of the portion 1 of the plate k, by means of a hinge k, k? similar to that of the door 2, is a lower portion 3 and on the back of this portion?) is a depression or recess between which and a cross shaft k carried by the side frames 7' is arranged an extensible device by means of which the portion 3 may be kept in close contact with the surface of the drum a, this socket piece 77 mounted on the cross shaft k and threaded internally and an externally screwed bolt or pin 7: one end of which engages the portion 3 while the opposite end thereof is received within the socket piece In. The portion'3 of the curved plate is is made (see plan view Fig. 3) with a pair of angled side scrapers m, m, and a central cutting-off knife n which work against the surface of the drum. The side. scrapers may be so inclined as to direct the dough to the cavity being filled. By means of the door 2 the converging chamber t may be readily cleaned when so desired.

In order t assist in the feeding of the doughtothe cavities the surface of the drum is preferably corrugated or-fiuted While the inner faces of the circumferential'fiange's a I a may beplain or corrugated or fluted. A

centritl w-vertica li dividingfknifemay be a r ranged in the convergingchamber t and may extend from the top thereof to the cuttingoff knife a at the bottom, or for only part ofthe way-: ,7 v

.Tn' riperation, the dough to .be divided, 1s

' Supplied to the hopper?) and the drum (1 is rotated*by' means of the pulley d andgear Wheels 6 e in' the direction indicated by'the arrow at-Fig. I As the drum a rotates the 'doughis fed, by the drum, into the converging chamber ,t where 'it is'pack'ed hr subjected' to pressure and forced into the cavi ties fl The lumps of dough are ,ejected I from Ythe-cavities by the action on the plungers got the cam h and fall down on to the conveyer ban'dc by means ofwhich they are v, rernbved." It w'ill be seenthat the machine is self-'feeding, the, plate 7c cotiperating with the'drumto force the dough, at the'proper pressure,"-in to thecavitiesgof the drum, As the portion 3, where it bears against the drum, wears away it can'betightened up again by turning the screw is.

'iflffsodesired there may befitte d in the hb perb an adjustable regulator o by means of which the passage of the dough from the hopperto the converging chamber "t may be regulated' This regulator consists of a plate o hinged at 0 within thehopper and having connected to it ascreweti spindle 0 which passes-through a screwed hole in the plate 71;

i and is provided at, the outside iof the hopper b with a hand wheelot -"It'fisobvious that, the machine may be made double, it 6,, with two drums a anda c'ommon hopper, the plate 7c being made doubleias indicated in dotted lines at Fig. 2150'. as} to provide a converging packing chamber for each drum. In this case the output would be doubled.

. Having now fully described our. invention what "we claim and desire to secure by LettersPatent .is: 1 v p p .1. A dough dividing machine having, in combination, a rotary drum with cavities therein, a hopper for the dough, a, plate permanently secured to the hopper and exe g a erehlero tiee n e wer am a tending down one side of the drum to the underside thereof so as to form, .iwith the drunij, a gradually converging feed chain;
